SPECIFICATION forming part of Letters Patent No. 712,803, dated.November 4, 1902. Application filed December 3,1901. Renewed Septenlher18, 1902. Serial No. 123,922. (No model.)

To all whom t may concern,.-

Be it known that I, CHARLESJ. JOHNSON, a citizen of the United States,residing at the city of St. Louis, State of Missouri, have inventedcertain new and useful Improvements in Gas-Machines, of which thefollowing is a specication.

My invention relates to an improved construction of apparatus formanufacturing gas 1o from gasolene, and is an improvement on the devicedescribed in United States Patent No. 673,542,tissued to my assignee andmyself on May 7, 1901.

The novel features are hereinafter specifically pointed out and claimed.

Referring to the drawings, which form a part of this specification,Figure I shows a vertical section taken through the tankwith the otherparts in elevation. Fig. II shows a vertical section through the deviceused to regulate the ow of gasolene and which is made the subject of anindependent application. Fig. III shows, partly in vertical section, theVpump used to' force the gasolene from the source of supply into thesaid regulator and thence to the tank. Fig. IVis a front elevation ofthe entire device, showing also the underground reservoir. Fig. V is atop view of the crank-arms, which are secured to the side of the tank.Fig. VI is a vertical section thereof. Fig. VII is a detail of theclutch and bracket on which said cranks pivot. Fig. VIII is a verticalsection of the box through which the reservoir is filled. Fig. IX is atop plan view of the entire appar-attrs. Fig. X is a horizontal sectionof `the watermotor. Fig. XI is a vertical section 'thereof through theline XI XI of Fig. X. Fig. XII is a top View of the piston and guidewhich operate the pumps. Fig. XIII is a side view thereof, taken alongthe lineX'III XIII of Fig.` XII. Fig. XIV is a detail view ofthe rollerof saidguide. Fig. XV is detail view of the standard which supports thecounteracting-springs; and Fig. XVI is a' detail view, partly insection, of the buffer to cushion the sleeve 49.

The samenumbers indicate the same parts throughout the several drawings.

l is the main tank or reservoir, within which motor.

'is placed a perforated partition 2, which sup- 'portsV theexcelsior orother material. i

, 4 is the piston-rod of a water-motor 5, and 6 and 6' are the two pipesleading to the ends of said motor from av pipe 7 in connection with asource of supply.Vv An arm Soperates a valve m4 in said pipe 7, which inturn connects with a lever 9. The diaphragm 10, controlled by thepressure in the tank 1, operates the lever 9, thus automaticallycontrolling the action of the water-motor.

11 is the reservoir for gasolene, preferably placed underground and somedistance away and which is filled through the box 12.,

13 is the pipe through which the gasolene is pumped for consumption, and14 is an overflow-pipe, through which `any excess flows back into thereservoir.Y It extends into a depression 15, forming a seal.

The piston-rod 4 of the motor 5 connects with an air-pu mp orcompression-cylinder 16, whose action forces air through the pipe 17intothe reservoir 1 below the partition 2. The pressure of'- thisV airagainst the diaphragm lOoperates Vthe lever 9 and in turn controls thepressure allowed through the This is similar tor theconstruction of myPatent No. 673,542,- abovereferred to.

Secured to the piston-rod 4 by meansv of a pin and slot is an arm 18,which is piv'oted at 19 rto a bracket 20, attached to the: reservoir 1.Rigid therewith is a bell-crank'21,to which is pivoted the piston-rod22.r This piston-'rod operates the gasolene-pump 23, .which drawsgasolene from the reservoir 11 through the pipe 13. Said pipe 13 isfurnished with a valve 24 to prevent a return flow, and the downstrokeof the piston 22 forces the gasolene out through the passage 25 into thepipe 26, also supplied with a valve 27, into the reghulator, 28. Thisregulator has an excess or overow'pipe 14, which `carries the excess Anauxiliary crank-arm 33 is pivoted at 19 and is held tightly against thearm 2l by means of the bolts 34 and springs 35. At 36 this arm ispivoted to a rod 37, provided with lugs 3S and 39, which strike a tixedbracket 40. This rod 37 is attached tothe stem of the valve 4l in theregulator 2S, and thus the action of the arm 33, limited in movement bythe lugs 38 and 39, controls the outflow of gasolene through the pipe29. It will be observed that on the movement of the arm 18, that sendsthe piston 22 down into the pump 23, and thus forces gasolene up throughpipe 26, will close the valve 41, and that the re-v verse motion willopen said valve when the regulator 2S is full, thus insuring a steadyand regular flow of gasolene into the tank l.

Secured to the bed-plate 42 (on which the whole device is supported) aretwo bearings 43, which support the ends of the rod 44. Movable on thisrod are two lugs 45, whose adjustment limits the movement of the arm 4G,which is secured by la bolt or clamp 4S to the sleeve 49. The end of therod 44 is attached to the bar 50, which is linked at 51 to the valveswhich operate and control the dow into the Water-motor 5.

A standard 52 is furnished with two openings, through which pass rods 53and 54. These rods are surrounded with coil-springs 55 and 56, bearingin opposite directions. Rod 54 is pivoted at 57 to the sleeve 49directly opposite the double incline 58. Linked to a pivoted roller 59by hook 60 and eye 61 is the rod 53, which serves to pull the roller 59tightly against the incline 5S and which counteracts the effect of thespring 56. Thus when the apex of the double incline 58 passes the roller59 it will be carried quickly and surely past the center, taking with itthe arm 46, which strikes the lugs 45, thus quickly operating the arm 50and links 51, which control the water-motor.

The piston-rod 4, operated by the watermotor and which also operates theair-compression cylinder 1G, has secured to it an arm 62, which isadapted to strike the stops 63, which in turn are rigid with the sleeve49, which carries the sleeve 49 slowly to the point where the roller 59is at the apex of incline 5S. Then the pull of the spring 55 hurries thesleeve onward. This takes with it the arm 4G, which strikes the lugs 45and in turn controls the rod 50 (as described) which opens and closesthe ports into the said Water-motor.

The arm 46 is moved from one side to the other by the lugs 45 andcarries the incline thereon under the roller 59. The movement To lessenthe jar, I place a buffer 47, bearing on acoilspring, at either end ofthe said sleeve 49.

XVhile I have described the motor as operated by water-pressure, I donot limit myself to this means, as steam or any other lluid underpressure may be used.

That I claim as new, and desire to secure by Letters Patent of theUnited States, is-

l. ln a gas apparatus, the combination of a reservoir, a motor, anair-pump operated by said motor, an oil-regulator adapted to control thesupply of gasolene in relation to the supply of air, and aregulating-valve controlled by the pressure within said reservoir andwhich is adapted to regulate the said motor and an overflow for theexcess of the gasolene from the regulator tothe reservoir; substantially as described.

2. In a gas apparatus, the combination of a motor, an air-pump operatedby said motor, a reservoir, a source of supply of gasolene, a pump forsaid gasolene, an oil-regulator, and a regulating-valve operated by thepressure within said reservoir, and a mechanism operated by said motorand controlling said regulator whereby a constant pressure of gas ismaintained in said reservoir and a defiector disposed beneath the-discharge end of the exit-pipe from the regulator, substantially asdescribed.

3. In a gas apparatus, the combination of a motor, a carbureting device,an oil-regulator, an air-pump operated by said motor, an arm secured tothe piston-rod of saidpump, a bellcrank, rigid with said arm, agasolene-pump operated by said bell-crank, a second bellcrank operatedby friction, and a regulatorarm attached to said second bell-crank, saidoil-regulator arm adapted to open and close the valve of said regulatorand hold the same in position while said motor-piston makes a completestroke.

4. In a gas-machine, the combination of an air-pump, a pump for thegasolene, a carbureter, a motor, and a means of controlling the flowtherein consisting of arms adapted to open and close the ports of saidmotor, a rod to which said arms are pivoted, lugs attached to said rod,a second arm secured to a sleeve and which is adapted to strike saidlugs, reciprocating springs adapted to impart motion to said sleeve, adouble-incline cam, a roller adapted to give said sleeve motionindependent of the movement of the piston-rod when the apex of said camis passed, substantially as described.
